Nepal, almost more than 20 districts felt shock of earthquake of 7.9 Richter Scale today at around 11:30 am.

Kathmandu?s iconic Bhimsen Tower, a popular tourist site offering stunning views across the city, has collapsed raising fears of significant loss of life. The tower, which was around 60 meters high, would have been especially busy on a Saturday. All that now remains is a jagged shard rising from a pile of rubble.

Moments after the earthquake struck, thousands of Kathmandu?s residents rushed onto the streets, gathering in the middle of the mains roads for safety. Many are still outside, too afraid to return home, following a series of strong aftershocks.

The streets are now packed with people inspecting the damage, but the atmosphere is calm, with the police, army and civilian volunteers managing the crowds.

Its been really a worst day in history of Nepal after 1990 B.S devastating earthquake. Bhaktapur, Gorkha, Lamjung are main districts effected by Earthquake. Nepal lost many historic monuments today many of which are listed in World Heritage List of UNESCO.

Effect on Environment::

Rocks are sliding down the hill, buildings are falling down and all things are mixed up in the same place. It can further cause loss of biodiversity. But no one cant do anything as if it is meant to happen, it happens at any cost. So it has also effect on environment too.

What general people believe about earthquake?

People have thought that when population density increases and leads to urbanisation, earth cant tolerate the heavy loads of buildings, monuments and population. So ultimately earthquake occurs due to overload.

Why do earthquake occurs?

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly the rocks catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus (on top of the ground) is called the epicentre of the earthquake.
